To all whom it may concern.-

Beit known that I, LOUIS C. CARTER, a citizen of the United States, residing at Ad vance, in the county of Parker and State'of Texas, have invented a new and useful Car-Coupling, of which the followingis a specification.

This invention relates to improvements in devices for coupling cars, and has for its ob- In the drawings illustrative of the invention, in which correspondingpartsare denoted by like designating characters, Figure 1 is a plan view of two opposing draw-heads with the improvements embotlied* therein. Fig. 2 is a side view thereof partly in section.

The improved device comprises a drawhead 10, having a longitudinal recess 11 opening outwardly from its forward end,- the rear portion of the draw-head constructed to t any of the various constructions of cars, both freight and passenger, but preferably for freight-cars employed for various .purposes for which the improved device is more `particularly adapted. Intersecting the cavity 11 is a vertical cavity 12, with the upper portion extended rearwardly above the longitudinal cavity, as at 13, while the rear side at 14 is curved rearwardly and merged into the bottom side of the longitudinal cavity. Movably disposed in the vertical cavity is ascatchpin 15, having its forward side convex, as at 16, and extending into the longitudinal cavity for a short distance and its rear side intermediately concaved, as at 17, Vand its lower rear side curving upwardly and rearwardly, as at 18, and merging into the lower side of the longitudinal cavity, as shown at the left in Fig. 2. The upper portion of the catchpin is provided with 'a longitudinal slot 19, through which a stop-bolt 2O passes, the bolt being tranversely disposed in the draw-head, as shown.

The catch-pin 15\is provided with suitable means, such as an eye 21, for the attachment of a lifting rodor lever operative from the sides and top of the car; but as these` applianees and their modes of operation are so well understood they are not illustrated. I do not, therefore, wish to be limited to the use of any specific device for this purpose, but

reserve the right to employ any suitable pinoperate against the concave portion when the draft is applied, and thus prevent the strains from exerting an upward force upon the catchpin, but, on the contrary, causing the strains to exert Aa positive downward force, Las will be obvious. The convex portion lb,` of the pin 15 extendinginto the forward portion of the longitudinal cavity,'as shown in Fig. 2, coacts with the concave rear portion 17 to effectively prevent any upward movement of the catch-pin while the strains are applied, as 'will also be obvious. By this means the pin 15 will be self-sustaining in its operative position and will not be released by any jarring motions to which the draw-heads may be subjected.

When coupling the cars, the link 22 will be manually inserted in one of the drawheads, if not already there, with the pins 15 in both draw-heads'disposed in their lowered or operative positions. Then as the cars are brought together the entering link striking the pin 15 causes its incline 18 to ride the part 14 and causes the lower end of the pin to swing inwardly and to rise upwardly into the extension 13 and permit the link to pass beneath the pin, the pin falling by gravity,

passing through the link, and returning to its former position automatically, and thereby completing the coupling.

The slot 19 and bolt 20 c'oact to regulate the movement of the catch-pin and prevent its displacement and are therefore important features of the invention.

The draw-head and other portions may be constructed of any suitable material and of any suitable size and strength to enable them to eectually resist the severe strains to ties and prevent the accumulation therein` of water, snow, or other foreign matter being reduced at the point where it passes through the bottom of the draw-head to prevent thev passage therethrough of the catch-pin.

Having thus described the invention, what I claim isl. The combination in a car-coupling, of a draw-head having a longitudinal recess and an intersecting vertical recess, said vertical recess extended rearwardly above said longitudinal recess and with its rear side curving toward and merging into the lower side of said longitudinal recess, a catch-pin movable within said vertical recess and with its rear side intermediately concaved and its lower rear side curved forwardly and vengaging said oppositely-curving wall of the vertical recess and with its forward side convex and projecting into said longitudinal recess, and a link inclosing said pin and engaging its concaved portion, substantially as specified.

2. The combination in a car-coupling, of a' draw-head having a longitudinal recess and an intersecting vertical recess, said vertical recess extended rearwardly above said longitudinal recess and with its rear side curving toward and merging into the lower side of said longitudinal recess, a catch-pin having a longitudinal slot operating over ya guidepin transversely disposed in said draw-head, and movable within said vertical recess and with its rear side intermediately-concaved rear edge and its lower rear side curving forwardly and engaging said oppositely-curvin g wall of the vertical recess, and with its forward side convex and extending into said longitudinal recess, and a link inclosing said pin and engaging its concaved portions, substantially as specified.

- 3. The'combination in a car-coupling, of a draW-headfhaving-a longitudinal recess and an intersecting vertical recess, said vertical recess extended rearwardly above said longitudinal recess and with its rear side curving toward and merging into the lower side of said longitudinal recess, a catch-pin movable within said vertical recess and having its rear side intcrmediately concaved and its lower rear side curved forwardly and engaging said oppositely-curving wall of the vertical recess and with its forward side convex and extending into said longitudinal recess, a link inclosing said pin rand supported by its concaved portion, and means operative from above or to one side of the cars for actuating the catch-pin, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signatureiu Witnesses:
